Preventing dental pain involves efforts to reduce the likelihood of its potential causes (e.g., tooth decay, gum disease, TMJ disorder). Preventive methods that may help include:

• Regular brushing and flossing. Brushing and flossing help remove food particles and plaque that stick to or between the teeth and gums. A soft brush may be less damaging to gums and tooth enamel.
  
  
• Fluoride. Using fluoride toothpastes and mouth rinses can help to strengthen teeth and prevent tooth decay that can cause dental pain.
  
  
• Sensitivity-reducing toothpastes. Certain toothpastes are designed to protect the teeth and decrease sensitivity to stimuli such as heat and cold. This can help prevent pain associated with sensitive teeth.
  
  
• Encourage saliva production. A lack of saliva (dry mouth) increases a person’s risk of developing tooth decay, which is the most common cause of dental pain. Saliva helps neutralize acids created by bacteria in the mouth and cleans away food particles and bacteria from the mouth. Chewing sugarless gum, drinking plenty of water and avoiding medications that may cause dry mouth can help.
  
  
• Regular dental examinations and cleanings. Dental experts recommend that people visit the dentist twice a year for examinations and cleanings. This helps to identify any oral problems early, while they are easy to treat and may help prevent dental pain.
  
  
• Avoid clenching or grinding the teeth. Avoiding these behaviors can reduce the likelihood of muscle soreness that can cause dental pain.
